GhostBlocks

Transformation Mode

• Added /gz mode <zone> [ghost|transform] to swap between barrier mode and morphing mode.
• In transform mode, ghost blocks morph directly into real world blocks layer-by-layer as the wave animation passes.
• Toggle modes in /gz menu using Middle Click or Shift + Left Click.

Collision & Physics Fixes

• Added Material.isCollidable() checks: non-solid blocks (vines, glow lichen, ladders, open trapdoors, sugar cane, torches, signs) no longer block movement.
• Fixed false wall collisions when walking or jumping on carpets, moss carpets, and bottom slabs.
• Replaced hard teleports with smooth outward push-back motion so players never get stuck in walls.
